These forged 3 7/8" big bore pistons are compatible with stock or S&S Super Stock® cylinder heads in Harley-Davidson® Twin Cam 88® and Twin Cam 88B™ engines. These pistons are designed to increase displacement of stock Twin Cam 88 engines to 95" and have a 5.3cc "pop up" dome for a slight compression increase. Piston weight is virtually identical to that of stock pistons in 88" motors, so rebalancing the stock flywheels is not necessary when installing S&S 92-1200 series pistons. 3 7/8" bore.
